Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a parts washing device for a washing machine, which is suitable for washing a die such as a die used in a tablet machine and other parts.

[0002]

2. Description of the Related Art Generally, stains on a mold of a tablet machine and various parts are cleaned and removed manually by an operator.

However, since such a cleaning operation requires a lot of manpower, it is difficult to deal with the situation when manpower is insufficient. Therefore, recently, a cleaning device for automatically cleaning the punch has been developed. This cleaning device
A net-like holding member is provided in the box opened up and down, and a large number of punches are held by the holding member in a posture in which the punch surfaces face upward. Then, by moving this box in a certain direction by a roller conveyor and passing it under a nozzle for jetting hot water downward, the dirt attached to each punch is washed away.

[0004]

However, in such a device, hot water is sprayed only from a limited direction to the pestle to be cleaned, so that an area where stains cannot be sufficiently removed easily occurs. . Further, in such an apparatus, since the cleaning process is transferred to the drying process while the hot water is still accumulated on the upward facing punch surface, impurities contained in the hot water are concentrated and adhere to the punch surface. Easy to invite. Further, there is a problem that it is difficult to sufficiently remove the oil content by washing only with warm water.

An object of the present invention is to eliminate such inconvenience.

[0006]

The present invention takes the following means in order to achieve such an object. That is, the parts washing device for a washing machine according to the present invention comprises a gantry that can rotate in a plane, a parts holding means that is arranged on the gantry and holds a plurality of parts of a tablet machine, and the gantry is driven to hold the parts A gantry drive mechanism for rotating the means in a plane in a fixed direction; and a liquid supply means for injecting a cleaning liquid such as warm water from a nozzle toward the component held by the component holding means and kept rotating. Characterize.

As a concrete example of the parts to be cleaned, a die such as a die can be cited.

As a concrete mode of the liquid supply means, one having an upper nozzle disposed substantially directly above the horizontally rotating component holding means and an upper inclined nozzle disposed obliquely upward is cited. it can. In order to improve the cleaning efficiency particularly in such a case, the component holding means is arranged in the opening of the gantry, the lower nozzle is arranged substantially directly under the opening, and the downward inclination is made obliquely downward. It is desirable to provide a nozzle. Moreover, in order to diversify the cleaning,
It is preferable to provide a switching valve for selectively injecting a cleaning liquid containing only warm water and a cleaning liquid containing a detergent mixed in the warm water.

[0009]

With such a structure, the cleaning liquid is sprayed from the nozzle of the water supply means toward the component which is rotating in the plane. Therefore, if at least one of the nozzles is arranged at a position deviated from the rotation axis of the gantry, the cleaning liquid will be sprayed from various directions to the parts, and the dirt will be washed out evenly. It becomes possible. In particular, when parts are installed in the opening of the gantry and nozzles are installed above and below the parts, the cleaning liquid can be sprayed from any direction toward the parts, so there is no leftover residue. You can Since powder as a raw material is often randomly attached to parts of the tablet machine after use, it is very meaningful to spray and wash the cleaning liquid from all directions in this way.
